Feb. 20 (UPI) -- Scientists have designed a new model to identify which organisms are capable of consuming other cells through a process called phagocytosis.The research, detailed this week in the journal Nature Ecology and Evolution, could help scientists more accurately simulate the evolution of early complex lifeforms.The earliest life forms on Earth were made up of prokaryotes, simple, single-celled organisms -- bacteria and archaea. More complex lifeforms, including animals, plants, fungi and protists, feature eukaryotic cells, larger cells with a variety of specialized components, including energy-producing organelles called mitochondria.But scientists have struggled to explain how eukaryotic cells evolved from prokaryotic cells. Some suggest the transformation was made possible by p...

Mexican archaeologists say they have excavated a stone sanctuary in a pond on the side of a volcano east of Mexico City that may have been built as a miniature model of the universe. The National Institute of Anthropology and History says the remnants of the stone "tetzacualco" were in the center of a natural pond below the Iztaccihuatl volcano at an elevation of nearly 13,000 feet. In addition to the sanctuary, decorative pieces associated with the rain god Tlaloc were found nearby. Archaeologist Iris del Rocio Hernandez Bautista says some Mesoamerican creation myths hold that the earth monster Cipactli floated on primeval waters and then split itself, thus creating the heavens and earth. She says the site at Nahualac could emulate that idea.Let's block ads! (Why?)

Dec. 8 (UPI) -- The "Out of Africa" model of early human migration and dispersal is outdated. As a new survey of research on the subject confirms, humans left Africa in waves, not in a single exodus.In the new survey, published this week in the journal Science, researchers at the Max Planck Institute for the Science of Human History in Germany and the University of Hawai'i at Manoa detail early human evolution revelations reported from Asia over the last decade.Improved genetic analysis technology, fossil recognition abilities and an emphasis on interdisciplinary research has helped scientists confirm the presence of humans in various parts of Asia much earlier than previously thought.According to genetic analysis, humans moving into Eurasia interbred with hominins along the way, including...
